It is even worse:

Between 20-25% of the European population is functionally illiterate. In other words: at least one citizen in five does not have the reading and writing skills they need for functioning in society, with all its consequences for education, employment, health care, welfare, social integration and political participation. ‘More than 73 million adults in the EU… do not have sufficient literacy levels to cope with the daily requirements of personal, social, and economic life’

So they are not just not reading any books, they literally can’t read books.

I would question your focus on growth. Yes, we all want this place to succeed. But do we really want this unlimited growth like Facebook, Reddit and all those other companies? Small communities are great, they give you a connection between users, they spark friendships and great discourse. Those are great. Yes, they are smaller than those multimillion user subreddits, but we’ve all seen those big subreddits slowly burning down. Dying to bots, to marketing spam, to low effort, popular comments, to reposts, to karma farming, to US politics. We’ve seen subreddit after subreddit dying to moderator burnout - because big subs are really hard to moderate, people will burn out. They are sacrificing their free time to deal with trolls, shills, putins guys and receive no compensation for that.

So maybe … let’s don’t replicate Reddit? Let’s focus on creating small, helpful communities and people will come.

And then there is the whole issue with private property - even if you’re not allowed to use metal detectors, there is nothing preventing you from digging holes in your own garden. But that is not what most people are doing - most suburbs are getting an archeological survey before they are build and then the construction will destroy everything else. So most metal detectors are running around on fields, through woods, some with private owners, some in state ownership

It totally does make sense. Amateurs with metal detectors are in most cases not really qualified to to archeological digs. And they really are not able do document them properly. Archeology is not only about the artifacts, but also about how they were found. Take a roman coin: If you buy it on Ebay or find it in the street, it is a roman coin. But if you find a roman coin f.e. on an ancient battlefield, you can use it to date the battle. That context gets lost when archeology is not done properly.

Also their finds are vanishing mostly into private collections. That really doesn’t matter with random coins, but f.e. the sky disc of Nebra, one of Europes most stunning bronze age finds, was dug up during an illegal private metal detector search and they then tried to sell it on the black market. So it does make sense to ban metal detector hunting.

Don’t listen to Axel Springer propaganda. They lie and distord facts. They want to make you angry.

Tourism also comes in seasons - a ski resort will be crowded in winter, but empty when the snow melts. A beach town is empty in the winter, but busy in the summer. Some cities are getting a huge influx of tourists for specific events, like Munich for the Oktoberfest. So your calculation won’t be accurate to measure the impact of tourism.

It also depends on what tourists are doing in the city and where they are staying. When they are visiting Disneyland Paris or some musical in Hamburg, they aren’t really bothering the locals. That’s different when they are all crowding in the old town of Dubrovnik.
